wxSFScaledDC Class Reference

Class acts as a wrapper for given DC class and provides modified drawing functions cooperating with the shape canvas able to draw scaled graphics. All drawing operations performed by the shapes should be done via this class otherwise the global scalling capabilities provided by the shape canvas wont be available. More...
